  1. You have any idea of chemistry? Your aluminate would be neutralized by alcohol.
  2. Personally, I make short bullets in the blank space most of the good books provide in the margin. Without reading the page I can reconstruct everything just by reading my short notes.
  3. Read a bit about optical isomerism and that would really help you.
  4. Such esterification would happen in highly acidic medium with very poor yield. And no, CO2 can't be made to leave just by heating (edit) in this case.
  5. Somehow, the link is not working for me. The crucible should have non-reacting components,besides having higher melting point than oxide.
  6. I think you mean oxidation and then reduction? You can oxidise propanol to carboxilic acid and then get propane using strong LiAlH4 or diborane/borane. If oxidation is not stron and you get aldehyde then HCl and Zn are used in the reduction. I dont clearly know the pathway reduction would follow and if alkene would be an intermediate.
  7. You can check that through an Ellingham diagram online. Any element whose curve is lying below the curve of particular oxide would reduce it at that temperature. However, only that knowledge wouldn't be enough to actually carry out the process.
  8. I made a little mistake in language. The number calculated would give no of distinct sets of 51 groups containing 4 members each.
  9. In metallurgical process they use Na3AlF6 or CaF2 to reduce melting point. They use this when they carry electrolysis, though.
  10. I am one of the ancient aliens, I survived many disasters,including the tv series.
  11. In conclusion the OP claims that there are no photons and only electromagnetic waves. How do you explain the photoelectric effect?
  12. There are few books that would be really helpfull because of their presentation and comprehensiveness. One for Algebra is Hall and Knights Higher Algebra and for geometry(plane) S.L. Loney's book. S.L Loney has written books on trignometery and co-ordinate geometry too. If you have already started doing from some other source then you can stick to that. As already pointed out, you will learn by doing yourself. Books do have solved examples after deriving formulas. Hide solution and think as much as you can. After giving it all you can tele your approach.
  13. It might be because of its high mass too. I was thinking of using BaSO4 as an inhibator.
  14. How would you make it gentle? With an inhibitor?
  15. Life is more complex than what you can see on a monitor in a finite interval. If thumb impressions of two people don't match, how can you expect to live other's life. You won't even get the same parents.
  16. I feel its the other way. Nitrogen in pyridine is less basic than secondary amine, consequently forms a weaker and longer bond. If I am incorrect then some MOT is involved with back bonding.
  17. I wonder why the substance is crystalline? It won't work either. If you go drastic you might loose the aromatic system.
  18. The number of days such a system can work is same as the number of distinct groups containing 4 members each which can be made out of 204 workers. 204!/[(4!^51)51!]
  19. Heating will only cause decarboxylation, and that too of just one carboxylic group. Sorry, I misread salicylic acid to be succinic acid. Theoretically, heating should work.
  20. Why do you think that water would attack as nucleophile. The ring isn't deactivated for a nucleophillic substitution.
  21. The point, I feel, is that the periodic classification is not the sole factor to predict properties. Lithium is alkali metal but differs from rest because of small size and high polarising power. Calling metal and Non metal just helps in predicting very simple properties.
  22. The validity of the law depends on how stretched the band initially is. The mass of projectile, I assume is small. I think, it would be incorrect to assume that the elastic constant measured for a band when vertically stretched would be same, in practice, for a band tied like a string to a bow; the stretching force not being verticalthis time.There is no denying the fact that hookes law is limited to materials and to the stretching force. Btw, rkt in my name is not for rocket.
  23. Clayden is very much recommended. Peter Sykes's 'A guidebook to mechanisms in Organic Chemistry' is my personal favourite. Short and Interesting.
  24. Hydrogen resembles alkali metals as it forms H+, halogens as it is one electron short of noble gas core. It even resembles group 15 as it has half filled orbital. In short, hydrogen is on its own.
